What is the typical turnaround time for recovery from sciatica ? i've had it for 2 weeks now and have been on medication for about a week.

It depends: It depends on the cause and the severity of the nerve entrapment. It can be days, weeks, months or not improve without surgery.

Weeks to Months: Generally most people can get relief from sciatic pain doing the conservative care within 3-6 weeks. If it persists after that, it can take up to 6 months to heal by itself. You may still be a candidate for epidural steroid injections that may help relieve the pain while your body heals itself.
